Abstract

A state of a ballast water treatment system of a ship detected by a variety of sensors is monitored by transmitting it to a control means provided with a data storage/transmission means. The control means transmits from a satellite communication means to a satellite communication means on the receiving side via a communication satellite, and a host computer receives it. The host computer analyzes and monitors information from the various sensors S1 to S6 and sends back an optimal operation state, which is received by the satellite communication means on the ship side via the communication satellite, and the control means maintains an operation of the ballast water treatment system based on instructions from the host computer. According to the remote monitoring device for a ballast water treatment system as above, the ballast water treatment system can be monitored and controlled from remote.

Claims

1. A remote monitoring device for a ballast water treatment system provided to a ship, wherein

the ballast water treatment system comprises a treatment effect confirmation means, an environment safety monitoring means, a control means, and a data storage/transmission means for treatment effect data and environment safety data connected to the treatment effect confirmation means and the environment safety monitoring means;

the data storage/transmission means are connected by wireless with a host computer provided away from the ship; and

the host computer monitors a state of the ballast water treatment system by using the control means based on treatment effect data and environment safety data received from the data storage/transmission means and maintains and manages operations of the ballast water treatment system to be proper.

2. The remote monitoring device for the ballast water treatment system according to claim 1, wherein the treatment effect confirmation means is one or more kinds selected from a residual oxidant sensor, an ultraviolet sensor, an oxidizing-reducing potentiometer, a dissolved oxygen meter, a level meter of a bactericidal agent tank, a flowmeter of a bactericidal agent, and a flowmeter of an electrolytic device.

3. The remote monitoring device for the ballast water treatment system according to claim 1, wherein the environment safety monitoring means is one or more kinds selected from a residual oxidant sensor, an oxidizing-reducing potentiometer, a level meter of a bactericidal-agent neutralizer tank, and a flowmeter of a neutralizer.

5. The remote monitoring device for the ballast water treatment system according to claim 2, wherein the environment safety monitoring means is one or more kinds selected from a residual oxidant sensor, an oxidizing-reducing potentiometer, a level meter of a bactericidal-agent neutralizer tank, and a flowmeter of a neutralizer.

4. A remote monitoring method for a ballast water treatment system provided to a ship, wherein:

treatment effect data and environment safety data obtained by a treatment effect confirmation means and an environment safety monitoring means provided to the ballast water treatment system are transmitted to a data storage/transmission means;

the data storage/transmission means transmits by wireless the data to a host computer provided away from the ship; and

the host computer monitors from remote a state of the ballast water treatment system by using the control means based on treatment effect data and environment safety data received from the data storage/transmission means and maintains and manages operations of the ballast water treatment system to be proper.
